Or this, if you want to remove CARC too:

I've used this on several parts already and it's fairly fast, definitely will remove carc and primer.
I know, I know, you said you wanted something that won't harm the CARC, but latex paint can be pretty tenacious.
Years ago I took an HVAC grill with about 30 years of primer-paint-paint-repaint-paint again (around 6 layers, I think) 'cause I couldn't find one in the same size and all that paint made that part of my house look like undergraduate/urban apartment slum.
I took it to a friend's gun shop and used his sand blaster with play sand (his specialty was building and refinishing M1919s and sand makes for a slightly rougher finish than glass bead blasting, not so many craters as with carbide media and it's cheap) and after about an hour with very little result - maybe 1-2 square inches of metal exposed - and left it with him to try in his spare time. Week later I went to his shop and he'd gotten maybe another 2 or 3 square inches stripped.
I'd already tried paint strippers before sand blasting. We tried several other paint strippers including the really toxic stuff without any luck. Finally found a supplier and replaced (recycled) the thing for about $20 delivered.
YMMV.
